IMPROVEMENT IN SECTIONAl. NUTS AND COLLARS.

Specification forming part of Letters Patent No. 216,338, dated June 10, 1879; application filed v August 22, 1878.

To all whom it may concern:

Be it known that I, EDGAR M. MORGAN, of Santa Cruz and State of California, have invented a new and useful Improvement in Sectional Collars; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being made to the accompan ying drawings, wherein- Figure l shows a longitudinal section of a rod or shaft with my improved collar placed thereon, and Fig. 2 a cross-section of the same.

The object of my invention is a new and improved collar adapted to be used upon a shaft to vkeep a nut or pulleyT in place and form a shoulder for that purpose so constructed that it can be easilynrnoyqed to another part of the rod or shaft, r removed altogether when desired.

My invention consists in making the collar in two parts-an inner part, composed in turn of two or more sections, and an outer or` clamping ring for holding the Iinner sections in place, the inner sections being provided with a rib to fit into a groove in the shaft or rod.

A represents a shaft or rod having a groove, a, cut in it at the point where it is desired to apply the collar. The collar is made in two parts. The inner part or ring is composed of two or more sections, c d, of such size that they will encircle the rod when placed thereon. These sections c d are conical or tapering a and holding the collar securely in place upon the shaft. The outer and inner parts may be keyed for additional security, if desired.

It will be seen that by my invention I provide a very convenient and effective collar, and one which can be easily removed when desired. It can also be used where the end of a shaft or rod is larger than the point at which it is to be placed.,

Having thus described my invention, I claim as new and desire to secure by Letters PatentrIhe combination, with the shaft A, provided with a groove, c, of the collar composed of the inner tapering sections, c d, with rib e, and the clamping-ring D, of tapering form, all substantially as shown, for the purpose set forth.

In witness whereof I have hereunto set my hand and seal.
